Fig. IV is a fragmentary cross sectional view To facilitate splicing ofthe yarns when ruptaken as indicated by the arrows IVIV in Figs. turesoccur, I have provided the means generally I and III. indicated at 22whereby the group of arms I2 55 rods 33, inward of the slide rods 29sustaining the yarn Spools IO'for each stocking blank B may beconcurrently swung back to inoperative position away from the rotorshafts I1. As shown, each such means 22 comprises a collar 23 which isrockable as well as slidable on the shaft l5, and which is provided withan upstanding grasp handle 24. Connected to the collar 23 is a shank 25which extends horizontally beneath the three spool sustaining arms l2 ofthe corresponding group and which is formed with hook fingers 26adapted, when the collar is shifted 'to' the right, to engage therespective arms to simultaneously swing them to retracted positionthereafter, by turning the handle 24 downward in Fig. IV. The end of theshank 25, it will be noted, is in each instance formed into a loop 26which freely embraces the corresponding fulcrum rod 15 and assists inguiding and supporting the retracting means 22. Normally, the retractingmeans 22 is held in the position shown in Fig. IV by contact of theprojecting boss 21 of the collar23 with the stop-rod 2|.

For the purpose of directing and tensioning the yarns Y, Y van dY enroute from the stocking blanks B to the spools I0, and forevenlydistributing the yarns on said spools,,I have provided atraversing carriage 28 which comprises a pair of laterally-spacedparallel sliderods 29 which are guided for end frames I and 20f themachine and which are joined at suitable intervals by cross heads 3|. Asshown, the cross heads 3| afford bosses 32 for the support of a pair ofsupplemental longitudinal and at a level somewhat below them. The rods29 and 33, it will be noted from Figs. III and IV, are respectivelyfitted with pig-tail eyes 35 and 36, there being a pair of such eyes foreach yarn withdrawn from the stocking blanks.

Reciprocatory movement is imparted to the traversing carriage 28 by arotary cam 31 having a circumferential groove 38 engaged by a roller 39on one of the cross heads 3! of said frame. The rotary cam 31 is securedto a shaft 50 journaled at one end in a boss 4| of the right-handendframe 2 of the machine, and at the other end in a bearing 42 on atransverse girt 43 supported between the upper frame longitudinals 3 and5..

The drive mechanism of the machine includes an electric motor 45 whichis mounted on a plate 46 bridging the lower cross bar 41 of the endframe 2 (Figs. I and II) and the lower longitudinals 4 and 5. To theshaft of the motor 45 is secured a pair of pulleys 48 of small diameter.One of these pulleys, 48, it will be observed from Fig. II, is connectedby a belt 49 with a somewhat larger pulley 50 on one of the spooldriving rotor shafts I1, from which latter motion is communicated atsynchronous speed to the other spool driving rotor shaft 11 by a crossbelt connection 5|. The other pulley ,48 on the shaft of the motor 45 isconnected by a belt 52 with a relatively large 'pulley 53 on atransmission shaft 54 with journal support in a bracket 55 mounted onthe plate 45 adjacent said motor. Alongside the pulley 53 onthetransmission shaft 54 is a small pulley 56 which is coordinated by abelt 51 with a large pulley 58 on the cam shaft 40. The spool drivingrotor shafts I! are thus rotatedat high speed, while the cam shaft 40isrotated at a predetermined slower speed for actuation of thetraversing carriage 28 to effect even distribution of the recoveredyarns on the spools Ill. The illustrated drive connections are of courseto be considered as endwise movement in bosses 30 of the back windingringless hosiery, the spools M by virtue of resting by gravityon therotor shafts having the capacity to slip so that one yarn may, in eachinstance, dwell until the selvages alongv opposite edges of the stockingblanks arecieared by the other two yarns, the align d reie 1 of thespools of each group permitting the cross and pass each other freely intheir passage back and forth as they are raveled from the blank to theend that the possibility of entangle ment and rupture is reduced to aminimum. Interchange of spools and yarn splicing or tying are easilyandquicklyeffected by the facilities providedfor the purpose. In backwinding stockings from very fine gauges, the yarns are passed throughthe eyes 35 on the slide rods 29 of the traversing frames only en routeto the receiving spools I5, suflicient tension being thus imposed onthem to insure back winding of said spools. In back winding stockingsmade from heavier gage yarns, the yarns are first passedthrough the eyes36 of the supplemental rods 33 of the traversing carriage, as shown indot-and-dash lines in Fig. IV, and then through the eyes 35 en route tothe spools i9, being thereby caused to traverses more devious path withincident imposition. of additional tension so as to avoid looseness ofthe mappings on the spools. The machine may ob viously be made to anylength according te the number of stocking blanks which are to be received at one time, and be made either of single bank design or ofdouble bank design as illustrated.

While I have described my improved winding machine as particularlyadapted to back winding ringless hosiery, it may nevertheless be usedfor back winding ordinary stocking blanks made from single yarns insteadof multiple yarns.

Having thus described my invention, I claim:
